To all whom it may concern:

State of California, have invented new and useful Improvements in Liquid-Atomizers, of which the following is a specification.

This invention relates to an atomizer or spraying. device particularly adapted for use in oil burners.

One of the objects of the present invention is to construct a simple, substantial atomizer or discharge nozzle, comprising a stationary and a turnable sleeve mounted one within the other, through which the oil is adapted to pass, said sleeves being provided with radially disposed admission slots which are adapted to beturned into and out of register with each other to regulate the oil flow therethrough.

Another object of the invention is to provide means. for instantly regulating the adjustment of one sleeve with relation to the other, thus enabling the fireman or oper- 'ator to instantly change the flame produced by the atomizer from a service fire to a stand-by or pilot light fire, or vice versa.

Further objects of the invention will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a longitudinal section of an oil burner showing the application of the atomizer. Fig. 2 is a central, longitudinal section through the outer end of the burnerv and atomizer. Fig. 3 is a cross section on line 33,.Fig. 1. Fig. 4 is a cross section on line 4-4, Fig. 1. Fig. 5 is a perspective view of the outside atomizer sleeve. Fig. 6 is a perspective view of theinterior sleeve.

Referring to the drawings, A indicates the discharge pipe of the burner which, in this instance, is connected with a suitable form of supply valve 2. Mounted on the outer end of the burner pipe and secured thereon, by means of a screw cap 3, is the atomizer proper. The atomizer consists of an exterior'sleeve member 4 provided with a head 5 which is engaged by the removable cap 3 to secure it, with connected sleeve,

discharge orifice 6 of small diameter, and the sleeve sectlon 4 is slotted longitudinally on opposite sides, as indicated at 7; theouter end of the slot being slightly enlarged,

as at 8, for purposes hereinafter to be described. v

Mountedinteriorly of sleeve 4 and turnable in relation therewith is an inner sleeve t) which is slotted at its opposite ends, as indlcated at 10 and 11; the slots 10 being preferably positioned tangentially. The sleeve 9 is centrally divided by a disk or partition 12 so that when the sleeves are positioned one within the other, as indicated in Fig. 2, an atomizing chamber 13 will be formed between the head 5 and partition 12, to which oil is admitted through the tangential slots 10 and from which the oil is permitted to discharge in the form of a whirling spray through the central discharge orifice 6. The oil admitted through valve 2 passes through the pipe A. It then enters the slots 7 and registering slots 10 into the atomizing chamber, and the volume of oil thus admitted is controlled by the register of slots 7 and 10. This is accomplished by turnin the inner sleeve 9 by means of a rod 14, w ich passes through pipe A and valve 2, being provided with a handle 15 at its outer end by which it may be turned; connection between the inner sleeve and the inner end of rod 14 being formed by providing a pin 16which passes through the rod and slots 11 formed on the outer end of sleeve 9. The pin 16 is also sufliciently long to pass through the enlarged portions 8 of slots 7, and the turning movement of the sleeve is, therefore, limited by the width of the enlarged portions 8 in the slots.

Referring to Fig. 1, it will be seen that the rod 14, with connected pin 16, has practically been turned to its limit in the direction of arrow a. The tangential slots 10 are in this position practically out of register with the communicating slots -7. Only a comparatively small volume or amount of oil can enter the atomizing chamber, or, in other words, just suflicient fuel is admitted to produce a pilot or stand-by fire. If it is desired, to increase the fire, it can be accomplished by turning the rod 14 in the direction opposite to arrow at until the pin 16 engages with the opposite walls of the slots 8. T The maximum opening or register between the slots 7 and 10 is thus produced, causing the atomizer to deliver or project its .full capacity, or, in other. words, provduce a'service fire which may be decreased by again turningthe rod in the opposite direction to decrease the register between the communicating slots.

- For .the purpose of preventing leakage or admission of oil between the two sleeves 4 and 9, a spring 17 has been provided, one

"end of which engages a shoulder 18 on the rod while the opposite end engages 'with vvthe outer end of sleeve 9,.forcing the sleeve cept through the tangential slots 10.

An oil burner constructed as hereshown -is simple and substantial inconstruction,

' cheaplymanufaotured and easily removed or taken apart. The control of oil passing therethrough or volume oi fire produced can be instantly changed, asitis only necessary to turn the rod handle 15 a slight. distance to secure the desired result; -The life of this atomizer is practically unlimited as any wear produced between the parts is automatically taken up by the spring 17, thus insuring'perfect operation and uniform results at all times.

The -materials and finish of the several parts of the atomizer are such as the experiehce and judgment ofthe manufacturer may dictate. Q a I wish it understood that various changes in form, proportions and details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is I 1. In combination with an atomizer head having a rear wall forming a seat, an apertured sleeve extending rearwardly of the head, and a member in said sleeve having an'open inner end the edge of which rota:v

tably and constantly engages in said seat so as to be closed by the wall and having an aperture registering with the sleeve aperture. p 1

2. Inan atomizer, a supply pipe, atip having axdis'charge orifice and a slotted extension having a central chamber formed thereinwith which the discharge orifice and slots communicate, the slots of the extension being widened at one end a sleeve turnably mounted in the chamber, said sleeve having a chamber formed at its inner end communicating with the discharge orifice and tangentially disposed slots opening into the sleeve chamber and adapted to register with the first named slots, means for turmng, the sleeve to bring the slots into and out of register with the first named chamber formed at.its inner end and communicating with the discharge orifice and tangentially disposed slots opening into the sleeve chamber and adapted to register with the first named slots, means for turning the sleeve to bring the .slots into and out of register with the first named slots, said means comprising a rod insertible into the outer end of the sleeve, and a pin in the rod extending through the slots in the sleeve and tip extension, the parts of the slots of the extension which receive said pin being of a width to allow the pin to move thereln and to, engage the side walls formed by the slots so as to restrict the extent of movement of the pin by engagement with said side walls.
